in this case johnson, not having tact is blurting out you stole a game to the developers of said game.
think about this: say you spend a great deal of time, money and effort to make something that you are extremely proud of. it takes a long time to finally get it out to people who are eagerly awaiting it's arrival. you're happy about people demanding your product, because all your effort has not gone to waste. the expense of making and distributing your thing is a great deal, and you need every bit of profit to make more things for people who are demanding them. now, with the thought of the money you need for the next things to make weighing on your mind, someone walks up to you and says, "hey! hows it going? i love your thing, it's totally cool? can you help with this and this? oh, by the way, i stole it and ripped you off. but it's cool, right? and i'll probably steal your next one, too. lol!"
wouldn't you be pissed off?
